Creating flash messages bootstrap style

I'm on a twitter bootstrap binge at the moment, it fills my soul with glee to start a new project with a base template that looks better than the usual dog's breakfast. Anyway, there are days when you just need a piece of code to blast in to your templates so that you can get on with your work. This is one of those and slapping the tremendous bootstrap success, warning and info messages into our normal flash message stylings is just what the doctor ordered. Here then, for your delectation, a small snippet of code to pop into your application layout in place of your usual flash message code that will style things up the bootstrap way. If you prefer, pull this out into a helper.....if you think that's the rails way. Personally, for small projects, I don't bother.

Adding an item to Linux Mint Cinnamon Menu

Last time I took you through installing Sublime Text 2 on Linux Mint . The trouble with doing the install the manual way as I showed and not using sudo apt-get is that you don't get the neat integration into the operating system so you wont find Sublime Text in your Menu and if you search it wont be there yet. Right click on the "Menu" in the bottom left and choose "Edit Menu". You should have something that looks like this: Excellent. On my install, Programming was not yet ticked, so I clicked the checkbox so that the Programming section would show up in my Applications menu. Then on the left hand side, you need to click Programming, or whichever other category you want to put Sublime Text into and then on the right, click the "New Item" and fill it in as follows: If you followed along when I installed Sublime Text, you aliased subl to launch Sublime Text. Clicking where the icon is will let you choose the icon location. I used the 48x48 icon...

Getting started with Ruby on Rails 3.2 and MiniTest - a Tutorial

For fun, I thought I would start a new Ruby on Rails project and use MiniTest instead of Test::Unit. Why? Well MiniTest is Ruby 1.9s testing framework dejour, and I suspect we will see more and more new projects adopt it. It has a built in mocking framework and RSpec like contextual syntax. You can probably get away with fewer gems in your Gemfile because of that. Getting started is always the hardest part - let's jump in with a new rails project rails new tddforme --skip-test-unit Standard stuff. MiniTest sits nicely next to Test::Unit, so you can leave it in if you prefer. I've left it out just to keep things neat and tidy for now. Now we update the old Gemfile: group :development, :test do gem "minitest" end and of course, bundle it all up.....from the command line: $ bundle Note that if you start experiencing strange errors when we get in to the generators later on, make sure you read about rails not finding a JavaScript runtime . Fire up...

Getting started with Docker

Docker, in the beginning, can be overwhelming. Tutorials often focus on creating a complex interaction between Dockerfiles, docker-compose, entrypoint scripts and networking. It can take hours to bring up a simple Rails application in Docker and I found that put me off the first few times I tried to play with it. I think a rapid feedback loop is essential for playing with a piece of technology. If you've never used Docker before, then this is the perfect post for you. I'll start you off on your docker journey and with a few simple commands, you'll be in a Docker container, running ruby interactively. You'll need to install Docker. On a Mac, I prefer to install Docker Desktop through homebrew: brew cask install docker If you're running Linux or Windows, read the official docs for install instructions. On your Mac, you should now have a Docker icon in your menu bar. Click on it and make sure it says "Docker desktop is running". Now open a terminal and ty...
